[Technical field to which the invention belongs]

 The present invention relates to paper for printing by an ink jet printer.

[0002]

[Prior art]

 Ink jet printers have recently become widespread with the development of personal computers. In particular, color printers have become available at low cost. For this reason, ink jet printers are widely used, and not only paper but also synthetic resin sheets are used as paper for the ink jet printer.

[0003] On the other hand, recently, swing stickers have been widely used for publicity advertising of products. This swing sticker is cut out in the desired shape and printed with letters and pictures for advertising, and it can swing, so it can be placed near the product to make it more noticeable in supermarkets and liquor stores. It is widely used in such places. Conventional swing stickers use stamped and printed shapes.However, as described above, ink jet printers can easily print any characters, patterns, etc. There is a need for a swing sticker that can advertise a great advertisement. However, conventional ink jet printing paper had to be cut out by itself after printing, and such a swing sticker could not be easily made.

[0004] Also, it is required that greeting cards, business cards, postcards, and the like can be created neatly by individuals. However, many conventional inkjet papers are of A4 size, and must be cut by themselves after printing. It was inconvenient.

Conventionally, printing is performed after a synthetic resin sheet is punched into a predetermined shape. In such a case, use the paper with the backing sheet and the synthetic resin sheet bonded together as printing paper, and cut the synthetic resin sheet completely into the specified shape except for the backing paper. I have. Printed with the backing, then peel off the synthetic resin sheet from the slightly adhesive sheet when using.

[0006]

[Problems to be solved by the invention]

 The problem to be solved by the present invention is to provide an ink jet printing paper which can solve the above-mentioned problems and can easily obtain a product having a desired shape.

Another object of the present invention is to eliminate the need for a conventional slightly adhesive sheet for backing.

[0008]

[Means for Solving the Problems]

 The present invention achieves the above object by providing an ink receiving layer on one side of a synthetic resin sheet, and performing a half-cut for separating from the ink receiving layer side to the middle of the thickness of the synthetic resin sheet. Achieved by inkjet printing paper characterized by

The synthetic resin sheet is preferably a polypropylene sheet. When the half cut formed from the ink receiving layer side forms a closed loop, it is preferable that a cut extending from the closed loop to the edge of the paper is provided. This cut may be a half cut, but it is preferable to completely cut the synthetic resin sheet from 1 mm to 10 mm from the edge.

【Example】

 Hereinafter, the present invention will be described in detail. FIG. 1 is an enlarged schematic sectional view of one embodiment of the ink jet printing paper of the present invention, and FIG. 2 is a plan view showing an example of a shape when the ink jet printing paper of the present invention is used for a swing sticker.

As shown in FIG. 1, the ink-jet printing paper 1 of the present invention has an ink receiving layer 12 provided on one surface of a synthetic resin sheet 11 serving as a main body. A cut 13 is made from the side of the ink receiving layer. The leading end 13a of the cut 13 is a half cut that does not reach below the thickness of the synthetic resin sheet and reaches only to the middle.

FIG. 2 is a plan view showing a case where the ink jet printing paper of the present invention is used for a swing sticker, and a predetermined closed loop shape is drawn by a cut 13 of a half cut. The cut 13 is made from the ink receiving layer side by a Thomson blade or the like. The Thomson blade is suitable for forming the cut 13 in the present invention because the Thomson blade is easily formed into an arbitrary shape and has a clean cut surface.

When the half-cut 13 is inserted from the opposite side (the side on which the ink-receiving layer is not provided on the synthetic resin sheet), when the cut-out is performed along the half-cut 13 after printing, the ink-receiving layer is formed into a film shape. , It may come off without being cut off well. For this reason, in the present invention, it is necessary to insert the half cut 13 from the ink receiving layer side.

In FIG. 2, a portion 2 surrounded by a closed loop cut 13 is a swing sticker, a large portion of which is an advertising portion 21 for printing advertising characters and pictures, and a portion 22 is attached to a holder or the like. Holding section. A portion 23 that connects the advertisement unit 21 and the holding unit 22 is provided. This shape is not limited to the shape shown in the figure, but can be any desired shape. In particular, the use of a Thomson blade makes it possible to easily perform half-cut of any shape.

A line indicated by reference numeral 14 is a cut connecting the edge of the printing paper 1 and the half cut 13 having a closed loop shape. If the sheet is completely cut from 1 to 10 mm from the edge, the cut line 14 can be easily cut out when cutting the closed loop shape after printing. In addition, if the completely cut portion is too long, it may not work properly when feeding paper with the printer. If the gap between the closed loop 13 and the edge of the paper 1 is 10 mm or more, the remaining portion is half. It is preferable to keep it in a cut state.

When the length from the shape of the closed loop 13 to the edge is short, the entire cut up to the position of the closed loop 13 may be a cut 14 in a completely cut state or a cut 14 in a half cut state. You may leave.

The synthetic resin sheet 11 used in the present invention is not particularly limited as long as it is a thermoplastic synthetic resin sheet such as a polypropylene sheet, a polyethylene sheet, and a polystyrene sheet. Particularly suitable for the half-cutting is a polypropylene sheet, and it is preferable to use a high transparency type or a white type, and a high quality printed matter can be obtained by using such a type. A polypropylene sheet having a thickness of about 0.05 to 3 mm is suitable as the printing paper of the present invention.

The ink receiving layer 12 formed on one side of the synthetic resin sheet 11 of the present invention may be formed by applying a conventionally known coating agent for the ink receiving layer.

The known coating agent for the ink receiving layer 12 is usually a mixture of a white pigment (for example, a white inorganic pigment such as talc or titanium dioxide, or an organic pigment such as polyethylene or styrene-based plastic pigment) and a binder. It is. Examples of the binder include resins such as polyvinyl alcohol, vinyl acetate, carboxymethyl cellulose, gelatin, conjugated diene copolymers such as methyl methacrylate-butadiene copolymer, latex, ethylene-vinyl acetate copolymer, and polyester. Is available.

As a coating agent for the ink receiving layer 12, for example, JF-IJ gloss clear from Teikoku Ink Manufacturing Co., Ltd., Diaromer IJ-2105 from Dainichi Seika Kogyo Co., Ltd., and Protein WRL-452 from Idemitsu Techno Fine Co., Ltd. Are commercially available. The ink receiving layer 12 can be formed by coating such a material to an appropriate thickness.

In the embodiment shown in FIG. 2, it is assumed that the swing sticker is cut out. However, the present invention is not limited to this. It can be used for cases and various stickers.

In particular, when used for postcards or the like, as shown in FIG. 3, characters can be written on a surface of the synthetic resin sheet 11 opposite to the side on which the ink jet receiving layer 12 is provided, using a writing implement such as a ballpoint pen. It is preferable to keep it. For this purpose, a coating layer 15 is formed so that a writing instrument can be written. The coating agent for forming such a coating layer 15 is composed of organic fine particles or inorganic fine particles and a polymer binder. Examples of the organic fine particles include polyethylene and polypropylene, and examples of the inorganic fine particles include various types such as carion, natural silica, and clay. Examples of the polymer binder include a thermosetting polyurethane resin, a polyester resin, and an acrylic resin.

[Effect of the invention]

 According to the present invention, an arbitrary shape is formed in advance on the inkjet printing paper in a half-cut state, so after printing desired characters and pictures in the shape, the half-cut portion is cut out by hand. Thus, a desired shape can be easily obtained. According to the present invention, a desired character or picture is printed on a standard size paper such as A4 printable by a printer, and then a half-cut portion is cut out by hand to easily create an irregular shape. It is.

According to the present invention, since the punching of the desired shape is in the half-cut state, a sheet for backing as in the related art is unnecessary, and a step of bonding the sheet for backing and the printing paper is unnecessary. However, it can be manufactured at a lower cost than conventional ones.

In the ink jet printing paper of the present invention, since the half cut is inserted from the ink receiving layer side, the ink receiving layer does not peel off when cutting out after printing.
